GLACIAL BOULDERS OF OUR FISHERIES.—HONEYMAN. 207 
In a plate of the Buccinidae of the Norwegian North Atlantic 
Expedition, we find the figures of two similar of reduced size. 
We assign ours to Buccinum wndatum, our allied boreal mollusc. 
In one of my walks on the shore of Point Pleasant, last summer, 
I observed an unusually Jarge number of the clusters of empty 
ege capsules of Purpura lapillus, cast ashore during a storm. 
I searched in vain, among them for our Ootheca. I opened the 
specimen of boulder (B). It was empty, all the fry had escaped. 
The next in prominence on our bolder (A) is a dark brown 
sponge, Myxilla lawsoni. We leave this and other sponges for 
another paper. Other attachés are polyzoa. Entangled in these 
we have a beautiful shell of the tiny Margarita undulata, 
another boreal mollusc. 
Mr. Willis reported this shell to Gould as found on our banks. 
A lower valve of Anomia was also found on the Sponge. 
Five small Gammari lay in the thick pendant plume of a 
sertularia. 
A Caprella, species? Was attached to the sponge. 
- A small Balanus adheres to the stone. 
Serpulw are abundant on the stone, and a campanularia on 
the sponge. 
One species of serpulw has a crypt-spire. <A spzrorbis is also 
attached to the Murgarita. Sertularida of more than one species 
are prominent. One has a number of branches forming the plume 
in which the yammari were esconced. The Campanularia with 
attached spirorbes trails over the sponge forming a net in which 
the Margarita was entangled. Bryozoa witha small encrusting 
sponge. Suberites incrustans ? complete the very interesting 
group of attachés of this Boulder (A). We number the 
boulders as they are described with large capitals for reference in 
this and the following Papers of our series. Lawson boulder 
(B) in addition to its Ootheca, has several bryozoa and two sessile 
foramenifera. 
Lawson boulder (C) has another Ootheca and an interesting 
sponge—Myailla. Also, a multitude of sessile foramenifera. 
As already stated, these three boulders are of ower Cambrian 
Quartzites. (D. E. F.) are also quartzite boulders. These are
